Jessica developed a cough and fever, but later exhibited other symptoms that have not been widely associated with the virus.
"I looked down, I was getting in the shower, I was like, 'Oh my gosh, my toe is turning blue," she recalled. "I felt like I had really bad blisters on it."
When she tried to lightly scratch an itch, her blood vessels ruptured.
Jessica's dermatologist, Dr. Shirley Chi, was stumped -- until she began examining research from overseas.
"When I first saw this mysterious rash, I just didn't know what to make of it," Chi said. "In northern Italy there was a study that showed that out of 148 patients at this hospital -- none of which had gotten prior medication -- one in five had a rash associated with their condition, COVID-19."

Chi emphasized the importance of individual patients contacting their doctor for treatment.
"That's why the American Academy of Dermatology is putting together a registry," and that's why it's important to contact your doctor if you have symptoms like this."
